  • This study was performed to investigate the contents of sulfites in 2, 770 dried marine products in Seoul Chung-Bu market from March to October in 1999. Sulfites of the samples were determined by Zn powder reduction method and Monnier-Williams's modified method. Eight samples of 2, 770 (0.29%) were detected over 30ppm in SO2 contents by Monnier-Williams's modified method. In samples detected over 30ppm, six dried filefishes(130.2~573.4ppm) were imported from Vietnam, same kind of other one(114.2ppm) was from China and the other one Alaska pollack(196.3ppm) was domestic. By Zn powder reduction method, 259 dried marine products (259/2, 770=9.35%) were positive reaction (1-30ppm). These were 93 dried shrimps, 53 filefish meats, 34 dried squids, 33 slices of dried pollacks and 17 sea mussel meats. So sulfites must be use commonly to prevent black spot and preserve for many dried shrimps, filefishes meats, dried squids etc. According to results, the quality test for the imported dried marine products must be reinforced to supply safety food for the citizens.

  • Eighty seven strains were isolated from 164 dried marine products(dried squid and dried alaska pollack etc) in Seoul Garak wholesale market. Among 87 isolates, twenty four E. faecalis and 4 E. faecium were identified by API strep kit. Twenty eight strains of E. faecalis, and E. faecium were resistant in streptomycin (95.6%), kanamycin (84.5%), gentamycin (66.7%), cephaloxin (97.8%), ampicillin/sulbactam (88.9%), ticarcillin(66.7%), amikacin (97.8%), sulfonamides (97.8%), ceftriaxone (75.6%), nalidixic acid (100.0%), and cefoxitin (100.0%), and were susceptible in amoxicillin/clavulanic acid(97.8%), chloramphenicol(95.6%), sulfamethoxazole/trimethoprim (97.8%), and tetracycline (71.1%). Also, ten strains of E. faecalis was resistant in $S-K-GM-CF-SAM-TIC-An-S_3-CRO-NA-FOX$ drugs simultaneously. Conclusively, E. faecalis strains from dried marine products were resistant on antibiotic drugs residue.

  • This survey was carried out to estimate the contents of heavy metals (Hg, Pb, Cd, and As) in 10 kinds of dried marine products (n=189) which are closely related to food resources. The contents of heavy metals were estimated by inductively coupled plasma spectrometer (ICP) and mercury analyzer. The values of heavy metals in dried marine products were as follows (Mean${\pm}$SD (range), mg/kg). The average contents of heavy metals in the dried marine products were Hg $0.058{\pm}0.069$ (0.002~0.502) mg/kg, Pb $0.178{\pm}0.598$ (ND~5.130) mg/kg, Cd $0.306{\pm}0.610$ (ND~6.802) mg/kg, As $5.282{\pm}6.158$ (ND~71.760) mg/kg. The range of heavy metal contents in dried marine products are low level, except of lead contents (n=2). In the comparison of heavy metal content by anchovy size, it was shown that cadmium, mercury and arsenic were meaningfully different. The contents of heavy metals by the shape of shrimp and Alaska Pollack were shown that the result of each group was meaningless. In the comparison imported production with domestic production, in the case of common squid, cadmium and arsenic were meaningfully different. The weekly average intakes of Hg, Pb and Cd from dried marine products takes about 1.17~11.52% of PTWI (Provisional Tolerable Weekly Intakes) that FAO/WHO Joint Food Additive and Contaminants Committee has set to evaluate their safeties.

  • We made a multi-layer conveyor sterilizing system using UV rays to prolong a storage period of dried marine products. The system is composed of 5 layer conveyor belt of 3 m long each, thus 15 m long in total. It is designed to radiate UV rays for 10 minutes the dried marine products, and can process 300 kg/hour. Eight UV lamps of 30 cm long and 15 W of power with 254 nm wave length are installed in parallel, 15 cm high above in each belt, and 40 lamps in total. The whole system is covered by 1 mm thick metal plates to block the UV rays except a front side which is covered with 5 mm thick plastic plates coated with UV protection film to survey inside of the system. A sterile ratio is about 99.97% with 10 minutes sterilization using this system.

  • This survey was conducted to monitor the food additives, heavy metals, and microbial contamination of the dried marine products like squids, pollacks, and shrimps, including jerked beef. They were purchased from supermarkets and traditional markets in Gwangju from February to December 2009. A total of 101 samples were tested. Sorbic acid, one of the additives, was detected in 29 samples of them (32.2%) and the contents were from 21.4 to 244.2 mg/kg. Among heavy metals, lead was detected, ranging from 0.000 to 0.594 mg/kg and cadmium, from 0.000 to 0.679 mg/kg and mercury, from 0.001 to 0.947 mg/kg. Sodium was detected, ranging from 0.6 to 1.7%. Aerobic bacteria were detected from 81 samples (80.2%), coliform bacteria, from 10 samples (9.9%) and Bacillus cereus, causing food poisoning, was isolated from 3 samples (3.0%).

  • The heavy metal (arsenic, chrome, and nickel) contents in dried marine products sold in market were investigated using ICP-MS to assess the associated health risk. Chrome and nickel were not detected at significant levels. However, arsenic was detected in all (21 specimens) dried crustacean products, including 10 (50%) among 20 dried mollusk specimens, 15 (13.9%) among 108 dried fish products, and 6 (17.1%) among 35 specimens of dried seaweed, which exceeded the set level for some dried agricultural products and medicinal herbs used in traditional medicine. Regulatory levels for heavy metal contents in marine products are not currently available. Thus, it is necessary to establish proper regulation and consistent monitoring of heavy metal contamination in marine products. Although the contamination levels of the investigated heavy metals do not seem harmful in terms of the statistical percentage of provisional tolerable weekly intake (%PTWI), consistent investigation of the health risk due to contamination of dried marine products by heavy metals is required.

  • ABS1'RACT-Comparative effects of gamma irradiation and ethylene oxide treatment on the sterilization, and physicochemical and sensory quality of dried marine products(shrimp, anchovy) were investigated. Population of mesophilic total bacteria, aerobic spores and tolerant bacteria of samples were $10^{3}-10^{7}/g,\;10^{7}\;to \;10^{4}/g\;and\;10^{2}\;to\;10^{6}/g$, respectively. Coliforms and molds were found only in dried shrimp as $10^{2}/g$. Mesophilic total bacteria, aerobic spores and acid tolerant bacteria were reduced by over 2 to 4 log cycles with irradiation of 5 to 7 kGy and they were completely sterilized by irradiation dose of 7 to 10 kGy. $D_{10}$ value of mesophilic total bacteria of samples ranged from 1.53 to 2.73 kGy. Coliforms and molds were sterilized at 5 to 7 kGy irradiation but ethylene oxide treatment proved insufficient to eliminate the microorgainsms. An optimum dose of irradiation was less detrimental than ethylene oxide treatment to phpicochemical properties of the samples, such as the pH, TBA value, TMA-N, amino acids, minerals and color difference. Sensory quality after three months of storage showed that the overall acceptability of irradiated sample was higher than that of the non treated control as well as ethylene oxide treated samples.amples.
